    Area of Science:

    • Phytochemistry
    • Natural Products Chemistry
    • Pharmacognosy

    Background:

    • Alkaloids are a diverse group of naturally occurring organic compounds that contain at least one nitrogen atom.
    • Many alkaloids exhibit significant pharmacological activities, making them valuable in medicine.
    • Systematic screening of plant biodiversity is crucial for discovering novel alkaloid sources.

    Purpose of the Study:

    • To conduct a large-scale screening of plant extracts for the presence of alkaloids.
    • To identify and quantify the proportion of plant species containing alkaloids.
    • To discover new alkaloid-containing plant species for future research and potential applications.

    Main Methods:

    • A total of 1000 diverse plant extracts were subjected to chemical tests for alkaloid detection.

    Related Experiment Videos

  • Standardized qualitative assays were employed for the preliminary identification of alkaloids.
  • Positive results were further analyzed to confirm the presence of alkaloids and identify new species.

    • Main Results:

    • Out of 1000 plant extracts screened, 185 tested positive for alkaloids, representing an 18.5% yield.
    • The screening successfully identified 107 previously undocumented alkaloid-containing plant species.
    • This represents a significant contribution to the known botanical sources of alkaloids.

    Conclusions:

    • The study demonstrates a notable prevalence of alkaloids in the screened plant population.
    • The discovery of 107 new alkaloid-containing species highlights the untapped potential of plant biodiversity.
    • These findings provide a foundation for further investigation into the chemical structures and bioactivities of newly identified plant alkaloids.
